I ran through the steps Derek outlines, and I do indeed see the odd behavior that he reports. I’ve never seen this before because this isn’t the usual sequence I go through to create my custom forms. My usual method is this:

Create a copy of the default form

Open the copy and either delete the original LFWP or convert it to XSLT. I usually delete it.

If I haven’t converted to XSLT, I add a new Data View: Data View / Insert Data View from the top menu

While everyone seems to say that you MUST leave the default LFWP on the page and hide it, I never do this, and I’ve never seen any adverse effects. (This is one for the SharePoint Myths series.)
